How to close dialog themed Activity

Question

I have a dialog themed activity that contains only a ProgressBar with a single TextView. The code of that activity looks like this:

public class ProgressDialog extends Activity{

TextView msg;
ProgressBar progressBar;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    this.requestWindowFeature(Window.FEATURE_NO_TITLE);

    setContentView(R.layout.progress_dialog);

    msg = (TextView)findViewById(R.id.progressMsg);
    progressBar = (ProgressBar)findViewById(R.id.progressBar);
    Intent intent = getIntent();
    String msgString = intent.getStringExtra("msg");
    msg.setText(msgString);

}

}

This represents a ProgressBar Dialog that I will use for my Project so that I have a same look and easy costumizable Dialog on all versions of Android.

The problem is how can I finish this activity from an AsyncTask onPostExecute() method if I start it in the onPreExecute() method as a normal activity. The AsyncTask is called in another Activity. I tried different things but have not managed to succeed. I tried:

• Simulate a back press button
• Using fragmentManager and activityManager
• Implementing a public method in the Activity that calls the finish() method for an activity

Please help! If you need some additional code let me know!

Best regards!

Answer 1

Write a method along these lines in the calling activity and call it to remove the dialog:

private void removeDialog() {
    Intent removeDialogIntent = new Intent(this, ProgressDialogActivity.class).setAction(ACTION_CLOSE_DIALOG);
    startActivity(removeDialogIntent);
}

And in the progressDialogActivity make sure to handle it:

@Override
protected void onNewIntent(Intent intent) {
    super.onNewIntent(intent);

    if (ACTION_CLOSE_DIALOG.equals(intent.getAction())){
        finish();
    }
}

You can stop the activity from a service or any other context, just add the relevant flags to the intent.

Having said that, personally I would use DialogFramgent and avoid all this mess, why do you need a dialog activity...?
